Power button doesn't work

Desktop Environment is KDE Plasma 6.6.2.
I setted power button function to "Turn off the screen".
I pressed power button, but the screen didn't turn off.
This issue occurs other functions.

I asked AI, Grok and Gemini.

Edit "/etc/systemd/logind.conf".

#Delete commentout
HandlePowerKey=ignore

But it didn't fix the issue.

does it actually registers?

Re: Power button doesn't work

There wasn't acpid, so I installed acpid package.

I tried to register it, but I don't know how to turn off screen with commands.

I think what 5hridhyan wanted to know was whether acpi_listen picks up the power button.

$ acpi_listen
# Press power button
button/power PBTN 00000080 00000000
button/power LNXPWRBN:00 00000080 00000001

acpi_listen recognites power button actions.

Re: Power button doesn't work

sorry for the confusion earlier, thanks seth for clarifying the @OP,  Mkants, can share the output of these?

loginctl seat-status seat0
grep HandlePowerKey /etc/systemd/logind.conf
ps aux | grep powerdevil
